I've seen kids zooming about on Heeleys, but Treadways' motorized shoes are firmly for Adult Use Only. The designer has entered them into the annual James Dyson Awards, and if successful could be put on the market. No more walking!

Treadways' founder Peter Treadway reckons they're better suited as an alternative to using the car or bus for short-haul journeys. Of course, I'm partial to cycling if I can (GoCycle's electric bike being my current obsession), but a zippy pair of lithium-polymer battery powered attachments that I can fold over my shoes would definitely get a test run at least.
